#Excel is a great tool but here are the 3 reasons I made the switch to #R.

True story.

#rstats #datascience

I used Excel for years.

I did VBA programming.

I used pivot tables, slicers, and I was an expert in all of the Excel functions.

I spent 10 years mastering Excel.

And the "power suite" of tools was coming out.

So why did I make the switch to R?

👉 The blue screen of death.

I remember the day I knew I needed to make a change.

It was Monday morning 10 minutes before my 10AM call with my CEO.

I began “refreshing” my Monday AM Excel Report.

Then it happened.

My computer froze and the screen turned dark blue!

What the heck! I was scrambling.

I had to do the presentation without numbers and explain that I wasn't fully prepared.

Ugh.

👉 Data is too big.

Over the next few weeks, the blue screen kept happening.

This was frustrating. 🤦‍♂️

I later found out why my Excel refresh locked my computer up.

👉 Excel craps out at 1 million rows.

My data had crossed the line.

And the result was a BIG BLUE SCREEN.

So what’s the alternative?

👉 Say NO to bandaids

I could have learned PowerQuery, but this seemed like a bandaid.

My data was growing too fast.

And, the real problem is that Excel could not do what I needed.

👉 I began learning R.

The single best choice I made was learning R.

I was able to fix all of the problems and scale my data analysis 1000X.

I was processing 1 GB of data like a hot knife through butter.

Which still isn’t that big, but I would never have been able w/ Excel.

👉 Has this happened to you?

If you are in my shoes, and Excel is getting you down, then hear me out.

It took me a long time to learn R. 5-years to really feel confident. And, a lot of trial & error.

But I have good news.

I have a free 40-minute webinar that consolidates my 10 years of knowledge learning R.

You will learn exactly which tools in R I found useful and have a roadmap to learn R.

What's Your Next Step?

It's simple.

Watch my free webinar and I'll give you the roadmap to becoming a 6-figure data scientist with R!

Enjoy.
